  • Aluminum hub resists corrosion with lightweight construction

  • Set screw locking secures hub to shaft
  • 7000 RPM maximum speed supports high-speed drives
  • Compatible with L100 spider elements for flexible coupling

Jaw Coupling Hub Aluminium 1 Inch

The Lovejoy AL1001 is an L100 size jaw coupling hub machined from aluminium with a 1 inch round bore and keyway. It uses a set screw locking method and straight jaw profile for general power transmission applications.

Speed And Torque Limits By Spider Material

Maximum rotational speed is 7,000 RPM. At 100 RPM the hub transmits 0.1 hp with a urethane spider, 0.66 hp with Buna N and 1.8 hp with Hytrel. Higher speeds reduce allowable horsepower proportionally.

Compatible Centre Elements For Required Capacity

The hub accepts L100H, L100N and L100U centre elements. Selecting the appropriate spider material provides the torque capacity needed; the hub itself does not limit torque beyond the spider ratings. Builds requiring higher torque or different bore sizes need alternative hub models.

Highlights

  • 1 inch bore fits standard shaft dimensions

Questions about this item

Which bore diameter should I choose for a 1 inch shaft?

The hub has a 1 in round bore with a 1/4 in keyway width and 1/8 in keyway depth, so it fits a 1 inch shaft directly.

What horsepower can this hub transmit at 100 RPM?

With a Buna-N spider it handles 0.66 hp, with a Hytrel spider 1.8 hp, and with a urethane spider 0.1 hp at 100 RPM.

What does the 7,000 RPM maximum speed mean for my drive?

It is the top rotational speed for the hub; do not exceed it, and ensure the chosen spider element is also rated for that speed.
